Abstract

Il disegno battistrada di un pneumatico radiale per autovettura ad elevate prestazioni comprende scanalature longitudinali oblique, inclinate rispetto alla direzione circonferenziale del pneumatico secondo un angolo compreso fra 20 e 200, con le estremità opposte assialmente scalate fra loro: esse possono essere inclinate tutte nel medesimo senso oppure convergenti, preferibilmente in modo simmetrico, verso il plano meridiano del pneumatico, specificatamente per i disegni direzionali.Le scanalature longitudinali sono associate con una pluralità di scanalature trasversali presentanti la loro porzione centrale inclinata in senso opposto a quello delle scanalature longitudinali, secondo un angolo compreso fra 30° ed 80°, rispetto alla direzione circonferenziale del pneumatico.La combinazione delle scanalature longitudinali e trasversali scendo le inclinazioni stabilite delimita tasselli che sviluppano sull'area d'impronta del pneumatico forze tangenziali che si combinano globalmente fra loro generando una forza risultante con la componente assiale (forza di deriva) di valore sostanzialmente nullo.
